Tamiya Nissan 300ZX IMSA-GTO - #58091 (Radio Controlled Model)

1/10 Scale Electric Racing Car - Group-C Chassis:

  Released by Tamiya on November 29, 1990, the Nissan 300ZX IMSA.GTO is a 1:10 Scale replica of the car driven by Steve Millen in the 1990 IMSA GTO Championship series.

Tamiya Nissan 300ZX IMSA-GTO - #58091 Group-C

  The chassis for this car was a short wheelbase version of the one used for the Mercedes Benz C11 (#58088) which was later designated the "Group-C" chassis.

  The configuration of the "Group-C" chassis was similar in a number of ways to the F101, not least in that it employed a ball differential in place of the older Orbital Gear type. This gave the car improved stability when cornering and smoother, controlled acceleration out of the corner.

  Now considered relatively rare, used and NIB examples are occasionally available.

Buying a Used Tamiya Nissan 300ZX IMSA-GTO
Touring Car (and What to look for)


   Buying a used Tamiya Nissan 300ZX IMSA-GTO Electric Touring Car, or any used RC Model, has a number of advantages. It is generally cheaper than new, ready built and may come with a variety of expensive hop-ups already installed. Cheap, pre-loved bargains are always becoming available. However, depending on the age of your purchase, it may need a little tender loving care before you can take it out on the back yard.

   The one thing you will always need is an instruction manual. If not supplied with your purchase, they can often be downloaded from the Tamiya website, or purchased separately on eBay. With an instruction manual, any problems with your model Touring Car you may discover can easily be fixed.

Dampers
   When you receive your used Tamiya Touring Car, make a general visual inspection of the chassis, front and rear wishbones, suspension shock towers etc, for any broken parts that may need to be replaced. Then, take a screwdriver and box spanner and check each self tapping screw and nut for security, taking care not to over tighten.

   Next, for those Tamiya models with oil filled shock absorbers, remove them from the chassis and dismantle the coil springs. The damper shafts should push in and pull out with a smooth action. If you feel a jolt as you change direction, this means the oil has leaked out and must be topped up. At the same time, change the O-Ring seals to prevent more leakage. Also check the damper shafts for damage. If they are scratched, change them as soon as possible.

   If the body shell of your Tamiya Nissan 300ZX IMSA-GTO is broken, ripped or damaged in any way, this can be easily repaired with rubber solution glue. Also, for added protection and if available for your Nissan 300ZX IMSA-GTO model, fit an under guard to stop dirt and gravel entering the chassis.

Titanium Turnbuckles
   Examine the drive shafts for wear and replace as required. If possible, change them for titanium. The steel shafts wear and bend too easily.

   If you intend to race your Nissan 300ZX IMSA-GTO Touring Car model at a competitive level, I would also recommend you obtain and fit titanium pivot shafts, turnbuckles, tie rods and steering rods.

   On Belt driven models, the Drive Belts need checking at regular intervals for wear, tension and damage. If deemed necessary, adjust the tensioning pulley until the belt can be depressed in the centre by no more than around 5mm. If the belt was slack, also examine the drive pulleys for wear. The teeth should provide a well seated fit for the belt teeth and not be rounded on the corners. If the belt teeth do not fit snugly, change the pulleys as soon as possible. For top level racing it may be prudent to replace all belts and pulleys after each race meeting.

   For Gear driven models, the gearbox of your used Touring Car should be opened up to check for gear wear and lubrication. A thin coat of grease is often used on internal gears and although this is fine for basic running around on the back yard, if you intend to race your Touring Car at a higher level, this should be removed and replaced with racing oil (ZX1 or Teflon Oil). Of course, this should be reapplied after each race meeting.

Spur Gears
   Gears are a weakness on all Touring Car RC models. Head on collisions can easily damage the gear teeth on nylon and plastic spur gears. Heavy impacts can also loosen the nuts or self tapping screws that hold the Electric Motor in Position, allowing the pinion gear to pull out of mesh slightly and rip the tops off the teeth on your spur gear. To minimise this possibility, fit bolts with locking nuts to the Electric Motor mount and remember to check them for security after every two or three runs.

   Ball joints always cause problems. For top level Electric Touring Car racing, the plastic ball connectors should be checked and if deemed necessary, changed after every meeting. A simple thing like a loose fitting connector popping off, could easily end your race, so better safe than sorry.

Servo Gears
   The Nissan 300ZX IMSA-GTO steering servo is also prone to damage. In high speed crash situations, the fragile gear teeth of the servo can be broken off, rendering your expensive servo useless, so be sure to obtain a good quality "Servo Saver". Check out my Servo Information article.

   If body roll on your Tamiya Nissan 300ZX IMSA-GTO is a problem, handling can be improved with the use of stabilizers, anti roll or sway bars, stiffer tuning springs and, or, thicker silicone oil in the dampers.

Ball Bearings
   If your used Tamiya Touring Car comes with plastic and sintered brass bushings (ring type bearings), check the shafts that run in them for wear. Dust and grit can get into these bearings and abrade the shafts. Therefore, you should replace them all with shielded ball bearings. If the model has been run with ring type bearings, you may have to change all the axles and driveshafts. For more information, take a look at my article, How to get the best from your Bearings.

   Finally, good luck with your Nissan 300ZX IMSA-GTO model and good racing.

Hints and Tips

Tires for RC Models

Sponge (Foam) Tires:

   Sponge Tires can be purchased either pre mounted, glued and trued on the rims, or separately. Fitting the Tires onto the rims can be messy, so here are a few tips to make it a bit easier.
   If you are fitting new Tires on old rims, make sure the old sponge Tire is completely removed. To do this, I recommend using a wood lathe and apiece of wood, at least 300mm long and more than the width of your wheels, with medium grit emery paper stuck to it ... sand paper will also work, but emery is harder wearing ... This will also be used for truing a wheel. (Described later)

How to Mount and Glue Sponge Tires onto Wheels/Rims.

1/   Mount the Tires on the rims. Make sure they are reasonably tight on the rims, too loose and you might have problems.

2/   I find this to be easier if either in the lathe, or on the car itself. (but be careful with that glue)
  Using your thumb and forefinger, lift up the Tire off the rim, then using a small spatula or a thin piece of rigid wood or plastic dipped in glue (I recommend Evo-Stik, Impact Adhesive) slip it in the gap, making sure both the Tire and the rim are smeared. Then lower the Tire back onto the rim and press it down. Turn the Tire approximately 60 degrees and repeat.

3/   Depending on the width of the Tire you may need to repeat the process on the inside also.

How to True Sponge Tires.

   Truing Sponge Tires is essential if you are serious about racing competitively. To do this you will need the piece of wood, as described earlier and a good pair of vernier or digital calipers.
   Sponge Tires will always wear unevenly, weather you race on Carpet or Tarmac. The outside wheels will always end a race smaller than the ones on the inside, so after each race I recommend swapping them over (unless you are fortunate to have a new set for each race) and dont forget to adjust the steering trim on your transmitter before the next race.

1/   Before starting, check each mounted Tire for diameter and order them smallest to largest. Start with the smallest and mount it in the lathe.

2/   Make sure you are wearing safety glasses before you start this procedure: Lay the sanding wood under the Tire so that it can be pivoted up from behind onto the Tire. Start the lathe spinning, so that as you stand infront of the Tire, it is rotating downwards. Slowly lift the sanding wood and try to hold it ridged as it comes up against the Tire. There will be a high point on the Tire that if you hold the bat rigid enough will eventually wear down until the Tire appears completely concentric. at this point stop the lathe and measure the diameter on the inside and outside of the width. If needs be, repeat the process until satisfied.
Repeat for each Tire, matching them in pairs for diameter.
If considered necessary also trim the sides.

Hints and Tips


Bearings

   If you are serious about your racing, looking after your bearings is essential if you are to remain competitive.
   My own experience is in both Off and On Road, National and International Car racing, but most of these tips could be useful to all forms of RC.

   Shields: The main problem with Ball Bearing Shields is they create friction and obviously the more you can reduce friction, the more efficient your bearings will be, so here's a tip that does just that.
   Wheel Bearings always come in pairs, positioned side by side. If you think about it, the two inside shields on each bearing are not required, so ... you can remove them using a small jewelers screwdriver ... simple. And in one fell swoop you have halved your wheel bearing friction.

   Cleaning: All Bearings need to be cleaned from time to time. Depending on how focused and competitive you are, this can be as often as after each race meeting, or just once or twice a year ... For Club Meetings once or twice a year might be all you need if you are easily beating your competition, but for the BIG meets you need that extra 5% or 10% just to be up with the rest.
What you need is a small glass jar, a jewelers screwdriver, an old tooth brush and some Isopropanol.
Remove the shields, then drop the bearings in the jar, add some Isopropanol, pop on the lid and shake well. Empty them out, give them a good brushing and make sure they spin free then repeat the process. Clean the shields separately. Once you are satisfied, lay them on a piece of kitchen roll and allow to dry.

   Lubrication: The arguments I have had about what lubrication to use you wouldn't believe. Some of the top racers of my day swore they didn't use any at all, but cleaned out the original lubrication and ran them dry ... they also admitted to fitting a new set after each meeting ... well, they were getting them for free.
My tip is, yes even with a new set of bearings, clean out the original lubrication (as described above) and with one shield in place use the thinnest oil you can find ... I recommend ZX1 (Zed Ex One) or sewing machine oil.
